Methodsfor predictingthe performanceof laser-trimmed film resistors taking into account the properties of the heat-affected zone (HAZ) are discussed. A figure of merit based npon a sensitivity fnnction called HAZ sensitivity, SHA z , is introduced which is useful for determining aging and temperature effects of an arbitrary film-resistor geometry with an arbitrary trim strategy. ~H4 z is also s...

Propensity score weighting is sensitive to model misspecification and outlying weights that can unduly influence results. The authors investigated whether trimming large weights downward can improve the performance of propensity score weighting and whether the benefits of trimming differ by propensity score estimation method. In a simulation study, the authors examined the performance of weight...

the periodic trimming of the long hairs growing at the distal end of the tail -switch trimming- is humane alternative of tail docking. the purpose of this study was to determine the influence of switch trimming on somatic cell count (scc), california mastitis test (cmt) and udder cleanliness of lactating cows in a free-stall dairy farm. in the present study, 219 healthy, pregnant holstein cows ...

An experiment was designed to compare BW and mortality of turkeys when three methods of beak trimming were utilized. Turkeys from six genetic lines were assigned to three beak trimming methods: arc beak trimming at hatching, hot-blade block trimming at 13 d, or hot-blade top-beak-only trimming at 13 d. Beak trimming method influenced 8-wk BW of three lines of females, but did not affect female ...

The resistance increase by transverse cutting is more quickly than by ordinate cutting when using laser trimming. Therefore, the precision and efficiency of laser trimming can be improved at low cost through reasonable design of the L-cut. In this paper, the finite element method is used to study the influence of L-cut on the resistance of chip resistor. Experiments proved that the qualitative ...

An experiment in forced vibration was conducted to study the fluidinduced rotordynamic force on an impeller whirling along a trajectory eccentric to its undeflected position. The prescribed whi l trajectory of the rotor is a circular orbit of a b e d radius. The force measured is a combination of a steady radial force due to volute asymmetries and an unsteady force due to the eccentric motion o...

Fluid dynamics simulations were applied for evaluating the suspension of particles in stirred vessels. The spatial distribution of particles throughout the vessel was characterized by a single parameter, here called the suspension quality (σ). Based on simulation results, a semi-empirical correlation was developed that correlated the suspension quality with the vessel geometry and solid and flu...

In this work, the effects of the types of frother (MIBC, pine oil, and A65) and operational parameters (impeller speed and air flow rate) on the flotation of quartz coarse particles was investigated using nano bubbles (NBs). Quartz particles of the size of -425+106 mm and three types of frother were used for the flotation experiments. Also the impeller speed was 600 to 1300 rpm, and the air flo...

Due to growth of mechanisation and automation, today’s industrial systems are becoming more complex. A small breakdown of any non-redundant machine component affects the operation of the entire system. To increase the availability and reliability, automated health monitoring and self-diagnostic capability (SDC) becoming essential to many industrial machineries like pumps, motors, etc. Condition...

Glucosidase II (GluII) is a glycan-trimming enzyme active on nascent glycoproteins in the endoplasmic reticulum (ER). It trims the middle and innermost glucose residues (Glc2 and Glc1) from N-linked glycans. The monoglucosylated glycan produced by the first GluII trimming reaction is recognized by calnexin/calreticulin and serves as the signal for entry into this folding pathway. GluII is a het...
